Oohhh brand new TM bag! These are getting so rare. Is it a shoulder carry bag? Structured bottom like these?
These are like 7 inches across bottom, 6.75 depth on the sides, at the bottom. They are hand/arm carry tho not shoulder. The handles are buttery soft and twist with your arm, so they are super comfy to arm carry, so the depth is not an issue at all.
8 inches of shoulder carry might be tricky as it would stick out a lot. Do u have a pic?! I think how structured/flexible the bag is would determine if its easily carried…..
